BOBBIN FOR BRAIDING MACHINES.

Application filed August 22, 1924.

This invention relates to an improved bobbin for braiding` machines, and has for one of its principal objects the provision ot a novel and useful bobbin of unusually simple construction and which, on account of such simple construction, is easy and economical of operation.

One of the principal features of this inn vention is the construction of a two-piece bobbin adapted particularly for use with braiding machines or the like, which will eliminate the necessity of the ordinary separate tubular core now used with such bobbins, and which shall be so constructed that it can be readily adapted for use with both a winding apparatus and a' braiding machine, as desired.

Another important object of this invention is the provision in a bobbin for braiding machines of a simple, yet eliicient twopiece construction, comprising simply a thread supporting tube and a removable head therefor, which shall be practically in destructible and exceedingly easy of operation.

Still another and further important obiect of this invention is to provide a method and apparatus for winding thread for application to braiding machines whereby practically double the amount of thread can bc applied to each spindle of a carrier, there by effecting a very considerable economy in operation. y i' @ther and further important objects` of this invention will be apparent from the disclosures in the accompanying drawings and following specification.

The invention, in a preferred form, is illustrated in the drawings and hereinafter more fully described.

In the drawings:

Figure 1 is a vertical elevation of the im proved bobbin of this invention showing the same as having a desired quantity of thread wound thereon and with the feed head in position ready for insertion into a braiding machine.

Figure 2 is a vertical elevation of the wound bobbin as it is delivered from a winding machine and before the feed head is applied thereto.

Figure. 3 is a top plan view of the removable feed head of the bobbin.

windingv tube constituting the original cord transfer element of the bobbin.

Figure G is a section of the bobbin head illustrating' a slight modilication of the at taching means therefor.

As shown in the drawings: 'y

The reference numeral 10 indicates generally a tube., preferably of metal or some similar wear-resisting material, which is, as illustrated, of a length slightly greater than the length of the wound cylinder of cord 14 which is applied to the tube 10, each end ofthe tube adapted to project beyond the ends of the wound cylinder 14. The thread twine or cord is applied to the tube 10 by an ordinary self supporting winding process commonly used in the winding of such bobbins for their. laterk transfer and inser tion into braiding machines. rllhe cylinder of wound thread or twine 14 is applied directly to the supporting tube 10, as best illustrated in Figure 2, and one end of the tube 10 is provided with screw threads as illustrated at 1G, whereby a ratchet feed disc 18 or the like may be readily attached thereto. The ratchet feed disc 18 is itted with ordinary ratchet surfaces 2O whereby the assembled bobbin with the thread 14 thereon may be properly rotated for feeding purposes in braiding machine.

As best illustrated in Figure 6, an ordinary bayonet slot 22 may be formed in a disc 12 similar to the disc 18 instead of the screw threads, if such a feature is desired, the bayonet slot 22 co-operating with an ordinary pin or the like passing through the end of the tube 10 in the usual manner. The tube 10 is of an internal diameter so as to fit neatly over the spindle of a braiding machine carrier, and to revolve thereon in the braiding process. l

The operation is as follows:

The tube 10 is preliminarily inserted into a ywinding machine and a length yof thread wound thereon in cylindrical form, as illustrated at 14vin Figure 2, the thread being wound in such a manner that the package is practically self-supporting at the ends.

Vhenever it is desiredy to transfer the wound tube 12 to a braiding machine the disc 18 is fitted thereto by means of either the screw threads or the bayonet slot, and the assembled bobbin with the thread or twine 14 wound thereon inserted into a braiding machine, where the thread 14 is unwound therefrom in the ordinary manner. The

empty bobhin can be evidently used over and over again.

It will be seen that herein is provided a two-piece bobbin particularly for use with braiding machines, which, by eliminating the ordinary cardboard tube, results in a more economical and satisfactory operation, and which, on account of its removable feed disc, provides a very simple construction and one which it is practically impossible to get out of order.

I am aware that many changes may be made and numerous details of construction Varied throughout a Wide range without departing from the principles of this inventhan as necessitated by the prior art tion, and I therefore do not purpose limiting the patent granted hereon otherwise I claim as my invention:

A bobbin for braiding machines, comprising' a ltube upcn which thread is directly wound, a head for the tube coinirising a removable ratchet feed disc mounted on one end of the tube, and corresponding screw threads on the tube and head for readily assembling the same, said screw threads Working in a direction opposite to the ratchet 'feed of the head.
